New API Certification Mark (Starburst Mark) In choosing an oil, you want the proper quality and vis- cosity, as well as one that will add to fuel economy. The following table lists the recommended viscosities and applicable temperatures. When adding oil, different brands may be used togeth- er as long as they are the same API classification and SAE viscosity as those recommended by SUBARU.
SAE viscosity No. and applicable temperature *: 5W-30 is preferred. Engine oil viscosity (thickness) affects fuel economy. Oils of lower viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is re- quired to properly lubricate the engine.
Use only engine oil with the recommended grade and viscosity.

(cid:132) Recommended grade and viscosity
under severe driving conditions
If the vehicle is used in desert areas, in areas with very high temperatures, or used for heavy-duty applica- tions such as towing a trailer, use of oil with the follow- ing grade and viscosities is recommended.
API classification SL (or SJ):
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
(cid:132) Synthetic oil You can use synthetic engine oil that meets the same requirements given for conventional engine oil. When using synthetic oil, you must use oil of the same clas- sification, viscosity and grade shown in this owner’s manual, and must follow the oil and filter changing in- tervals shown in the maintenance schedule.

Cooling system
Never attempt to remove the radiator cap until the engine has been shut off and has cooled down completely. Since the coolant is under pressure, you may suffer serious burns from a spray of boiling hot coolant when the cap is re- moved.
(cid:121) The cooling system has been filled at the fac- tory with a high quality, corrosion-inhibiting, year-around coolant which provides protection against freezing down to –33°F (–36°C). For adding, use genuine SUBARU coolant or an equivalent: a mixture of 50% soft water and 50% ethylene-glycol basis coolant. Use of improper coolants may result in corrosion in the cooling system. It is important to maintain protection against freezing and corrosion, even if freezing temperatures are not expected. Never mix dif- ferent kinds of coolant. (cid:121) Do not splash the engine coolant over paint-
ed parts. The alcohol contained in the engine coolant may damage the paint surface.
(cid:132) Engine coolant (cid:84) Checking the coolant level
Maintenance and service
(cid:132) Cooling fan, hose and connections Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature. If the radiator cooling fan does not operate even when the engine coolant temperature gauge exceeds the normal operating range, the cooling fan circuit may be defective. Check the fuse and replace it if necessary. If the fuse is not blown, have the cooling system checked by your SUBARU dealer. If frequent addition of coolant is necessary, there may be a leak in the engine cooling system. It is recom- mended that the cooling system and connections be checked for leaks, damage, or looseness.

Automatic transmission fluid (cid:132) Checking the fluid level The automatic transmission fluid expands largely as its temperature rises; the fluid level differs according to fluid temperature. Therefore, there are two different scales for checking the level of hot fluid and cold fluid on the dipstick. Though the fluid level can be checked without warm- ing up the fluid on the “COLD” range, we recommend checking the fluid level when the fluid is at operating temperature. (cid:84) Checking the fluid level when the fluid is hot 1. Drive the vehicle several miles to raise the temper- ature of the transmission fluid up to normal operating temperature; 158 to 176°F (70 to 80°C) is normal. 2. Park the vehicle on a level surface and set the park- ing brake. 3. First shift the selector lever in each position. Then shift it in the “P” position, and run the engine at idling speed.

If the parking brake lever stroke is not within the specified range, have the brake system checked and adjusted at your SUBARU dealer.
Tires and wheels (cid:132) Types of tires You should be familiar with type of tires present on your vehicle. The factory-fitted 17-inch tires on the WRX-STi are summer tires. The factory-fitted tires on other versions are all-season tires. The 17-inch tires that can be deal- er-fitted on the WRX as an option are summer tires. (cid:84) All season tires All season tires are designed to provide an adequate measure of traction, handling and braking perfor- mance in year-round driving including snowy and icy road conditions. However all season tires do not offer as much traction performance as winter (snow) tires in heavy or loose snow or on icy roads. All season tires are identified by “ALL SEASON” and/ or “M+S” (Mud & Snow) on the tire sidewall. (cid:84) Summer tires Summer tires are high-speed capability tires best suit- ed for highway driving under dry conditions. Summer tires are inadequate for driving on slippery roads such as on snow-covered or icy roads. If you drive your vehicle on snow-covered or icy roads, we strongly recommend the use of winter (snow) tires.
Maintenance and service
When installing winter tires, be sure to replace all four tires. (cid:84) Winter (snow) tires Winter tires are best suited for driving on snow-cov- ered and icy roads. However winter tires do not per- form as well as summer tires and all season tires on roads other than snow-covered and icy roads.
(cid:132) Tire inspection Check on a daily basis that the tires are free from se- rious damage, nails, and stones. At the same time, check the tires for abnormal wear. Contact your SUBARU dealer immediately if you find any problem. NOTE (cid:121) When the wheels and tires strike curbs or are subjected to harsh treatment as when the vehicle is driven on a rough surface, they can suffer dam- age that cannot be seen with the naked eye. This type of damage does not become evident until time has passed. Try not to drive over curbs, pot- holes or on other rough surfaces. If doing so is un- avoidable, keep the vehicle’s speed down to a walking pace or less, and approach the curbs as squarely as possible. Also, make sure the tires are

Maintenance and service
not pressed against the curb when you park the vehicle. (cid:121) If you feel unusual vibration while driving or find it difficult to steer the vehicle in a straight line, one of the tires and/or wheels may be damaged. Drive slowly to the nearest authorized SUBARU dealer and have the vehicle inspected.
(cid:132) Tire pressures and wear Maintaining the correct tire pressures helps to maxi- mize the tires’ service lives and is essential for good running performance. Check and, if necessary, adjust the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop) and be- fore any long journey.
11-48
UGB510BA
Check the tire pressures when the tires are cold. Use a pressure gauge to adjust the tire pressures to the values shown on the tire placard. The tire placard is lo- cated on the door pillar on the driver’s side. Driving even a short distance warms up the tires and increases the tire pressures. Also, the tire pressures are affected by the outside temperature. It is best to check tire pressure outdoors before driving the vehi- cle. When a tire becomes warm, the air inside it expands, causing the tire pressure to increase. Be careful not to mistakenly release air from a warm tire to reduce its pressure.
NOTE (cid:121) The air pressure in a tire increases by approxi- mately 4.3 psi (30 kPa, 0.3 kgf/cm2) when the tire becomes warm. (cid:121) The tires are considered cold when the vehicle has been parked for at least three hours or has been driven less than one mile (1.6 km).
Do not let air out of warm tires to adjust pres- sure. Doing so will result in low tire pressure.
Incorrect tire pressures detract from controllability and ride comfort, and they cause the tires to wear abnor- mally.

Rolling resistance is high, so fuel consumption is also higher.
Ride comfort is poor. Also, the tire magnifies the ef- fects of road-surface bumps and dips, possibly result- ing in vehicle damage. If the tire placard shows tire pressures for the vehicle when fully loaded and for the vehicle when towing a trailer, adjust the tire pressures to the values that match current loading conditions.
Driving at high speeds with excessively low tire pressures can cause the tires to deform severe-

(cid:132) Wear indicators
Maintenance and service
(cid:132) Wheel balance Each wheel was correctly balanced when your vehicle was new, but the wheels will become unbalanced as the tires become worn during use. Wheel imbalance causes the steering wheel to vibrate slightly at certain vehicle speeds and detracts from the vehicle’s straight-line stability. It can also cause steering and suspension system problems and abnormal tire wear. If you suspect that the wheels are not correctly bal- anced, have them checked and adjusted by your SUBARU dealer. Also have them adjusted after tire re- pairs and after tire rotation. NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the vehicle’s run- ning stability. Contact your SUBARU dealer if you notice abnormal tire wear. *: The suspension system is designed to hold each wheel at a certain alignment (relative to the other wheels and to the road) for optimum straight-line stability and cornering perfor-

A) New tread B) Worn tread 1) Tread wear indicator Each tire incorporates a tread wear indicator, which becomes visible when the depth of the tread grooves decreases to 0.063 in (1.6 mm). A tire must be re- placed when the tread wear indicator appears as a solid band across the tread.
– CONTINUED – 11-51
Maintenance and service
When a tire’s tread wear indicator becomes vis- ible, the tire is worn beyond the acceptable limit and must be replaced immediately. With a tire in this condition, driving at high speeds in wet weather can cause the vehicle to hydroplane. The resulting loss of vehicle control can lead to an accident.
NOTE For safety, inspect tire tread regularly and replace the tires before their tread wear indicators become visible.
11-52
(cid:132) Tire rotation
HSB056BA
Tire wear varies from wheel to wheel. To maximize the life of each tire and ensure that the tires wear uniform- ly, it is best to rotate the tires every 7,500 miles (12,500 km). Rotating the tires involves switching the front and rear tires on the right hand side of the vehicle and similarly switching the front and rear tires on the left hand side of the vehicle. (Each tire must be kept on its original side of the vehicle.) Replace any damaged or unevenly worn tire at the time of rotation. After tire rotation, adjust the tire pres- sures and make sure the wheel nuts are correctly tightened.
After driving approximately 600 miles (1,000 km), check the wheel nuts again and retighten any nut that has become loose.
(cid:132) Tire replacement The wheels and tires are important and integral parts of your vehicle’s design; they cannot be changed arbi- trarily. The tires fitted as standard equipment are opti- mally matched to the characteristics of the vehicle and were selected to give the best possible combination of running performance, ride comfort, and service life. It is essential for every tire to have a size and construc- tion matching those shown on the tire placard and to have a speed symbol and load index matching those shown on the tire placard. Using tires of a non-specified size detracts from con- trollability, ride comfort, braking performance, speed- ometer accuracy and odometer accuracy. It also cre- ates incorrect body-to-tire clearances and inappropri- ately changes the vehicle’s ground clearance. All four tires must be the same in terms of manufactur- er, brand (tread pattern), construction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equipment. For safe vehicle operation, SUBARU recommends re-
Maintenance and service
placing all four tires at the same time.
(cid:121) All four tires must be the same in terms of manufacturer, brand (tread pattern), construc- tion, degree of wear, speed symbol, load index and size. Mixing tires of different types, sizes or degrees of wear can result in damage to vehi- cle’s power train. Use of different types or sizes of tires can also dangerously reduce controlla- bility and braking performance and can lead to an accident. (cid:121) Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce control- lability, resulting in an accident.
(cid:132) Wheel replacement When replacing wheels due, for example, to damage, make sure the replacement wheels match the specifi- cations of the wheels that are fitted as standard equip- ment. Replacement wheels are available from SUBARU dealers.
– CONTINUED – 11-53
Maintenance and service
Use only those wheels that are specified for your vehicle. Wheels not meeting specifica- tions could interfere with brake caliper opera- tion and may cause the tires to rub against the wheel well housing during turns. The resulting loss of vehicle control could lead to an acci- dent.
NOTE When any of the wheels is removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque.
Aluminum wheels Aluminum wheels can be scratched and damaged easily. Handle them carefully to maintain their appear- ance, performance, and safety. (cid:121) When any of the wheels is removed and replaced for tire rotation or to change a flat, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque. (cid:121) Never apply oil to the threaded parts, wheel nuts, or tapered surface of the wheel. (cid:121) Never let the wheel rub against sharp protrusions or curbs. (cid:121) Be sure to fit tire chains on uniformly and completely around the tire, otherwise the chains may scratch the wheel. (cid:121) When wheel nuts, balance weights, or the center cap is replaced, be sure to replace them with genuine SUBARU parts designed for aluminum wheels.

Replacement of wiper blades Grease, wax, insects, or other material on the wind- shield or the wiper blade results in jerky wiper opera- tion and streaking on the glass. If you cannot remove the streaks after operating the windshield washer or if the wiper operation is jerky, clean the outer surface of the windshield (or rear window) and the wiper blades using a sponge or soft cloth with a neutral detergent or mild-abrasive cleaner. After cleaning, rinse the wind- shield and wiper blades with clean water. The wind- shield is clean if beads do not form when you rinse the windshield with water.
Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzene. This will cause deterioration of the wiper blades.
If you cannot eliminate the streaking even after follow- ing this method, replace the wiper blades using the fol- lowing procedures:
